The physicians in Problem 3-36 have been approached by a market research firm that offers to perform a study of the market at a fee of $5,000. The market researchers claim their experience enables them to use Bayes’ theorem to make the following statements of probability.
probability of a favorable market given a favorable study = 0.82
probability of an unfavorable market given a favorable study = 0.18
probability of a favorable market given an unfavorable study = 0.11
probability of an unfavorable market given an unfavorable study = 0.89
probability of a favorable research study = 0.55
probability of an unfavorable research study = 0.45
